Question

I have a custom view EMViewController with a tableview as a subview. I want EMViewController to double as the controller for the subview, so I have it set as the delegate and dataSource.

// EMViewController.h
@interface EMViewController : UIViewController <UITableViewDelegate, UITableViewDataSource>
...
// EMViewController.m
- (void)viewDidLoad {
    [super viewDidLoad];
    self.eTableView.delegate = self;
    self.eTableView.dataSource = self;
}

I’m populating the data with an asynchronous array/dictionary from Facebook, so once I have the data, I run

[self.eTableView reloadData]

For the UITableViewDataSource protocol methods, I implemented the following:

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
    NSLog(@"returns sections 0"); // This appears in my log
    return 0;
}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
    NSLog(@"returning count %d", [self.eList count]); // never shows up
    return [self.eList count];
}

- (EMTableViewCell *)tableView:(EMTableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    // configure the cell
    NSLog(@"index: %d", indexPath); // never shows up
    ...
}

So far, I have already tried:

• making sure my storyboard is connected up
• checking/rechecking the delegate/dataSource being set in viewDidLoad
• completely restarting/clean-building my app just in case
• creating a placeholder UIView subclass (although I’m not changing much)
• creating a customUITableViewCell class with outlets for my custom layout (images, 3 labels)
• testing out strong/weak references to the tableView outlet

Any advice would be appreciated. I think my problem is similar to this question, except I’m trying to add the tableview as a subview. My end goal is to populate the cells with a custom format that includes an image and three labels. Thanks!

Answer 1

Return 1 section instead of returning 0 sections

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
    return 1;
}
